I mentioned the restart because it is so unusual for Windows. however, if a new software version replaces a version already in memory, a restart is necessary. BTW, I loved my Mac, but I do have a much larger array of software that works on my pc, and for someone who knows what they are doing, problems are rare. One of the concerns I had about Windows 8 was using the new UI, but after a couple of hours, I am already getting proficient. Using start8 allows me to hit the left windows key to go to the old UI and start menu if I get stuck, while the right Windows key takes me back to Metro.I've yet to figure out a simple way to exit from metro Apps, but haven't spent the time since I am busy loading software, and I have a ton of it.I also want to clone my HD to a SSD, but I can't work on that right away.

Part of the problem is that Canon ships the original software, then you install....then later you can download new updates from the Canon website BUT NOT the entire new software.

Technically... is not true, the updaters actually look for the product registry entries then install the new version overwriting the old one completely. I have seen this with EOS Utility, Canon Digital Photo Professional, Raw Codec, Style Editor. So I assume is the same with the rest.

I do not use original CD, just download the so called updates, make sure my registry has the entries in it, for example:
